Of all the games to erase playtime data for this is probably the most egregious offender, as it launched with the Switch day one, and folks are proud of the effort they've put into their save files.
Nintendo has been doing a lot to make its latest console worth owning, and the library of games is steadily growing in the eShop every day.
Nintendo has shared more details about the Switch playtime glitch. It is pretty unbelievable being able to play The Legend of Zelda on my big television at home but then being able to undock the system and continue my game on the go. It began with The Legend of Zelda: Breath of the Wild and soon spread to other games on the console. In this massive sandbox-style game, Mario uses fun new hat-based abilities like cap throw, cap jump and capture with his new partner Cappy.
To close out 2017, Nintendo launched a sequel to the original Xenoblade Chronicles RPG series, Xenoblade Chronicles 2. Unfortunately it seems that potentially due to a bug, the activity log of the Switch has been wiped on its first anniversary, much to the annoyance of many gamers. It did not, however, indicate what may be causing the games to reset, leaving players to speculate. Usually companies tend to upgrade the hardware on their consoles on their new consoles, but it looks like Nintendo will be putting their focus into other aspects of the Switch for this year instead. This includes games from publishers like EA, Capcom, Psyonix, Take-Two Interactive, Ubisoft and Bethesda, to popular "Nindies" content, indie games on Nintendo Switch made by independent publishers, including Stardew Valley from Chucklefish LTD, Overcooked: Special Edition from Team 17 and Shovel Knight: Treasure Trove from Yacht Club Games.
Nintendo has since acknowledged the issue in a tweet, stating "Some Nintendo owners' play activity information is displaying incorrectly".
